Visa and Property Purchase Legal Assistance (Cascais)

We are moving to Portugal from the US and will be applying for a residency visa and permit. We have a quote from a local (Lisbon) law firm for Protected content for assistance in completing the documents, etc., but that seems very expensive to me. Does anyone have experience with this or a feel for whether this is the going rate? (The same firm quoted us a 1.25% rate for legal assistance on our property purchase and I would also appreciate any feedback on that). Thanks!Dave
